FYI - I also had both. I had a 7100t from October - February, and switch to a 7290. I was getting tired of retyping words (Suretype is good, but not perfect), and could not get over the screen washing out in daylight. 1000 emails per month is 35 / day (30 day month) or 45 / month for a 22 day "work month". That is not heavy by my standards. How many minutes are you on the phone? Do you need a speakerphone (which I freely admit I miss since it is not on the 7290).
